Perform the impossible when you make an ordinary ping pong ball float in mid-air! Learn how to do this super cool science feat in just a few minutes.
Watch this video and follow the step-by-step instructions to get started!
Check out this short video to learn how to make a ping pong ball float:
Step 1: What You'll Need
You only need two things to perform this science experiment.
Ping pong ball
Drinking straw (preferably a bendy straw)
Step 2: Bend the Straw
For the best results, use a bendy straw instead of a regular straight straw. Bend the neck 90 degrees so it points straight up.
Step 3: Position the Ball
Get into position! While holding the straw with one hand, hold the ping pong ball over the end.
Got a feel for it? Good! Now, get ready to make it float.
Step 4: Levitation!
Take a deep breath! You're going to need all the "lung power" you can muster to keep your ping pong ball airborne.
Blow a constant breath of air into the straw under the ping pong ball. If the air pressure is strong enough, it will lift the ball off the tip of the straw!
You may need to try again, blowing even harder next time! Make sure you take breaks between attempts - you don't want to get light-headed! The ball should be able to float at least one inch off the straw.
How Does it Work?
This amazing trick works because of air pressure. The air coming from the straw is moving faster than the air around it, and this means that it also has a lower air pressure than the air around it. So the ball is kept within the column of lower air pressure because of the higher-pressure air surrounding it.
Pretty cool, huh? Try doing this trick with a friend, brother, or sister and see if you can play "keep it up", passing the ping pong ball between yourselves.
